Water filter

The present invention relates to a water filter, in particularly a water filter with an improving structure in a manner which provides a dedicated water filter or a special water filter to reduce the possibility of interchangeability or replacement by water filters with poor quality.

Currently, the demands for water filter apparatuses are becoming more and more popular and focused. Therefore, manufacturers are always aiming for water filter apparatuses which are diversely designed to meet the variety demands of the user at the highest level. The internal components of the water filter apparatus are focused as well for improving not only variety of functions and shapes, but also positioning by different qualities and brands, for example typical water filters or high quality water filters for example.

One among those internal components of the water filter apparatus is a water filter in a configuration of a filter container containing a water filter cartridge therein, such as pre-filtration filter containers for example. For general and popular designs, the water filters and the water filter cartridges are usually provided with a relatively simplified configuration/shape and with a high interchangeability. Therefore, the water filter cartridges without quality assurance are still possible to easily replace for the water filter cartridges with high quality and positioned as premium brands. This not only affects the quality of the product of the customer but also affects the reputation of the manufacturer.

As for an example, a typical water filteris shown in,, and, substantially including a water filter cartridge body, a first cap, and a second cap. The first capand the second cap, are usually the same to each other, with a central holefor water is capable to flow out therefrom and an annular-shaped areafor arranging a watertight seal. When placing inside the filter container, supposing that the first cap(similar as for the second cap) is placed to adjoin with the filter container body bottom, the central holewill be communicated to the filter container outlet (not shown in the drawings), the outer surface of the first capfaces to the inner surface of the filter container body bottom will be pressed tightly with the inner surface of the filter container body bottom and providing a watertight joint in a face-to-face manner corresponding with the annular-shaped area. The mentioned design may be known as a relatively popular design in the market, is manufactured by several manufacturers with different qualities. In addition, although the annular-shaped area may be with relatively different sizes, it is still possible to make a watertight joint in a face-to-face manner as for the same type of the filter container. This may lead to a situation in which replacements or miscellaneous uses of poor products for customers can happen.

To overcome this problem, several water filters in the market using distinctive brand identifying sets, however this may not favorably solve the problem of using miscellaneous products with poor quality due to the awareness of the customers. Several customers may be not good at assessing and distinguishing the quality difference between various brands. Moreover, those distinctive brand identifying sets are possible to be faked.

Thus, there is a need for providing a new improvement of a water filter to overcome the mentioned replacements or miscellaneous uses of the water filter with high quality by the water filter with poor quality. In addition, there is also a need for providing a water filter with a favorable robust structure, ensuring for installing, using, and replacing conveniently.

Intoillustrating a water filter according to an embodiment of the present invention.

According to the embodiment, the water filter substantially including a water filter cartridgeis contained inside the filter container.

As shown in, the water filter cartridgeincluding a water filter cartridge body, a water filter cartridge outlet caphaving a water filter cartridge outlet, and a water filter cartridge sealing cap.

In general, the water filter cartridge bodymay be made from one or more filtering materials, and in a hollow cylinder form with a central hollow space.

According to the embodiment, one end of the water filter cartridge bodyis coupled with the water filter cartridge outlet capso that the central hollow space of water filter cartridge bodyis communicated with the water filter cartridge outlet, and the another end of the water filter cartridge bodyis coupled with the water filter cartridge sealing capso that the central hollow space of the water filter cartridge bodyis sealed at said another end. The water filter cartridge outletis in a hollow cylinder form protruding from one surface of the water filter cartridge outlet cap.

As shown in, the filter containerincluding a filter container body, a filter container cap, a filter container inlet-IN, and a filter container outlet-OUT (seeand). The filter container inlet-IN and the filter container outlet-OUT are arranged at the filter container body bottom. The filter container bodyhaving a filter container outlet cylinder hole(see,,, and), is provided at the filter container body bottom for receiving the water filter cartridge outlet, so that when water flows into the filter containerthrough the filter container inlet-IN will surround the water filter cartridgeand flows through the water filter cartridge bodyinto the central hollow space of the water filter cartridge body, and flows to the filter container outlet-OUT through the water filter cartridge outlet

According to one or more embodiment, the filter container bodyhaving ribs(see,,, and) provided at an inner surface of the filter container body bottom to reinforce for the filter container body bottom and providing gaps placed between the inner surface of the filter container body bottom and the outer surface of the water filter cartridge outlet capwhich is defined as a surface facing toward to the inner surface of the filter container body bottom.

The embodied design is completely different in comparison to the design of the typical water filter providing replacements or miscellaneous uses of the water filter cartridges with different quality become impossible. In particular, several typical water filters intended to a design which provides a watertight joint in a face-to-face manner corresponding to the outer surface of the water filter cartridge cap, will be impossible to couple and arrange inside the filter container with the design according to the present invention, because that when using the typical water filter, the ribsaccording the design of the present invention which provides the gaps placed between the inner surface of the filter container body bottom and the outer surface of the water filter cartridge outlet cap, not allow to form a watertight joint in a face-to-face manner, and therefore said miscellaneous use or replacement of the typical water filter for the water filter according to the present invention becomes impossible.

In addition, the water filters generally arrange the filter container outlet at the center of the filter container body bottom and the filter container inlet deviate to a side at the filter container body bottom.

As for the design of the typical water filter, the filter container inlet need to deviate out of the area where the watertight joint in a face-to-face manner is formed. This may be understood that positions which is possible to arrange the filter container inlet is limited. In case of the area of the watertight joint in a face-to-face manner is large may affect to the water circulation between a side with the filter container inlet of the filter container body bottom and the remain side of the filter container body bottom.

As for the design according to the present invention, because the ribseliminating said area which is needed to form said watertight joint in a face-to-face manner, may significantly avoid the limitation relating to positions which is possible to arrange the above mentioned filter container inlet, also the ribsprovide the gaps placed between the inner surface of the filter container body bottom and the outer surface of the water filter cartridge outlet cap, is considered to increase the circulation of water between a side with the filter container inlet of the filter container body bottom and the remain side of the filter container body bottom.
